To all whom t may concern.:

Be it known that I, DAVID FRonHLIcH, a citizen of the United States, anda resident of the city of New York, borough of Brooklyn, in the countyof Kings and State of New York, have invented a new and Improved AwningRoller, of which the following is a full, clear, and exact description.

This invention relates to improvements in means for raising and loweringawnings, and has particular reference to an awning roller.

An object of the invention is to facilitate the raising and lowering ofan awning by providing means in connection with the awning roller whichwill effectively guide the awning as the same is raised and lowered andprevent the awning from coming in contact with the means utilized toaccomplish such operations.

The above and other objects will appear more clearly from the followingdetail description, when taken in connection with the accompanyingdrawing, which illustrates a preferred embodiment of the inventive idea.

In the drawing- Figure 1 is a fragmentary front elevation of theexterior of a window showing an awning in lowered position and the meansfor operating said awning;

Figure 2 is an enlarged fragmentary longitudinal section through aportion of the mechanism for operating the awning roller and showing theinvention applied thereto; and

Figure 3 is an end elevation of the means shown in Figure 2.

Referring more particularly to the accompanying drawing, the numeral 4indicates an awning which is designed to be wound upon the roller 5 andwhich has its lower edge connected to rods 6, only one of which is shownin the drawing, said rods being in turn pivoted to suitable plates 7secured to the wall of the building adjacent the window, as is customaryin constructions of this character. A vertically disposed shaft 8 hasits lower end mounted in a housing 9 in which suitable gearing (notshown) of any desired character is arranged and which may be operated bya crank insertable into an opening 10 in the housing 9. The upper end ofthe shaft 8 carries a bevel gear 11, which meshes with a similar gear 12having a stub shaft 13, one end of which is mounted in the housing 14and the other end project- Serial No. 607,420.

ing into the adjacent end of the roller 5 and secured thereto in anysuitable manner. The construction so far described is well known andforms no part of the present invention. The present inventioncontemplates the provision of a means in the nature of a shield 15,which is interposed between the roller 5 and theI gearing for operatingthe same for the purpose of guiding the awning when the same is beingraised and lowered and for preventing said awning from coming in contactwith the gears 11 and 12, which would otherwise result in a mutilationof the awning. The shield 15 is formed of a single sheet of material,preferably circular in formation and having a central opening 16 forreceiving the portion of the stub shaft 13 which projects into the endof the roller 5. The central portion of the shield 15 is secured to therear face of the gear 12 by suitable fasteners 17. The portion of theplate forming the shield adjacent the periphery thereof is bent toprovide an annular fiange 18, which is of sufficient width to enclosethe gear 12 within the shield and also overlap the portions of the gears11 and 12 at the point where said gears intermesh.

From the foregoing' description it will be apparent that when the awningis being raised and wound upon the roller 5, the same will be properlyguided upon the roller by the shield 15, which will prevent the awningfrom extending beyond the adjacent end of the roller should an unevenwinding of said awning occur. In this event the edge of the awning wouldengage the flange 18 and be diverted back onto the awning. The flange 18also prevents the awning, in the case of an uneven winding thereof, fromcoming in contact with the gears 11 and 12 at points where the sameintermesh thereby minimizing the possibility of the awning becoming tornor mutilated by said gearing.

What is claimed is:

In a device for raising and lowering awnings, an awning roller forreceiving an awning, a shaft extending from one end of said roller,gears for operating said shaft to rotate said roller, and a shieldconsisting of a plate secured to one of said gears and having an openingfor receiving said shaft, said plate being bent between its outer edgeand the portion thereof forming the edge of said opening to provide anannular flange disposed diagonally with respect to the remaining portionof the plate and to the -axis of rotation of said shaft and beingcapable of diverting the awning back on to the roller Should a portionof said vawning corne in contact With said flange during the raising orlowering of the awning, said lange being also of a Width suicient toencircle the periphery of 'the gear towhich said plate is secured andpartially encircle the other gear which cooperates with the first namedgear A"to prevent contact of the awning With said gears.
